Green Pixel Software

Mobile Software Engineering - iOS & Android

About

Green Pixel Software is me, Christopher O'Brien, a mobile engineer with a passion
for the product.

I’ve worked as an iOS Developer since 2011 across multiple industries such as
sports betting, event management and broadcasting. I believe strongly in the engineering team
working closely with the product team
to build stable and scalable applications with great UI and UX. The devil is truly in the details
and focusing on them is what produces an amazing application.

I see myself as a well-rounded mobile engineer, having also worked across a variety of
Android projects since 2011. In the past year I have focused on expanding my skill
set to become more of a
Full-Stack engineer, working on server-side projects in Spring
(Java and Groovy), along with web front-end projects using
Angular 2.

I believe that having a clearly defined but open-minded approach to software engineering helps
to produce best results.

Testimonials

“I couldn't recommend Chris enough - he's absolutely the kind of guy you want on your
team. He's passionate about iOS development, always keeps up-to-date with the latest
technologies and is continuously looking for better ways to produce award-wining software.
He has an excellent grip on Agile methodologies (he served as scrum master on the Betfair
iOS team for several months), coached other members on the team on TDD & interviewed
possible candidates for roles on the iOS team. Time and time again, he drove the team to do
'the right thing' instead of 'the quick hack' and this proved to be invaluable when it came
to maintaining a healthy codebase. I'd look forward to working with Chris again in the
future.”

— Sean O'Shea | Principal Software Engineer

“Christopher got a long deserved promotion whilst I was working along side him for 3
months back in 2014. It was clear he progressed incredibly quickly and has gone on to really
shine in developing some awesome apps. He's now at the top of his game (and definitely not
one to stop improving). I would never hesitate working with him again.”

— James Hartt | Senior iOS Engineer
